Title: Fuel injection Pump
IPC: F02M41/14
Filed: 1980-07-21
Abstract: A fuel injection pump for supplying fuel to an internal combustion engine includes a plunger 21 reciprocable within a bore by cams 22 on a cam ring.

Title: Electromagnetic radiation sensors
Inventor: REES HUW DAVID
IPC: H01Q1/38
Filed: 1982-03-04
Abstract: A sensor comprises an antenna (141) of metal strip on a high resistivity semiconductor substrate, and one or more mixer diodes (43A to D) integrated in the substrate material and connecting adjacent antenna limbs (141A & B; 141 B & C; 141C & D; 141D & A). The antenna may be a single dipole, or may consist of a pair of crossed dipoles. For a crossed dipole antenna, one antenna limb (141D) is split along its length to enable extraction of the mixed signal - this is developed across the split portions (155, 157). Antennae (141), as above, may be assembled in closed-packed array, and the substrate material shaped to converge radiation onto these antennae. <IMAGE>
Patent GB-2097615-A (GB)
Title: Solid state load protection system having electronic simulation of motor heating
IPC: H02H3/093
Filed: 1982-04-26
Abstract: A solid-state load protection system having electronic simulation of motor M heating characteristics uses a current sensing function 14 so as to produce an output signal which is related to the current therein. Attached to the current sensing function 14 is an inverse time delay circuit 50 which has a signal path for charging and discharging a capacitor 26. Depending on the voltage across the capacitor which is related to the thermal state of the load, the inverse time delay circuit which is monitoring the voltage will initiate either a time-out or trip sequence of a reset sequence. The time before time- out or reset is proportional to the voltage across the capacitor. An output function 52 which is connected to the overcurrent and timing function upon receiving a trip signal causes a light emitting diode to conduct and also deenergizes a contactor 16 through which a current source is connected to the load. Upon receiving a reset signal the output function prohibits the light- emitting diode from conducting and energizes a contactor thereby connecting the current source with the load. <IMAGE>

Title: Cleaving laminated material
Inventor: DANDO KEITH
IPC: B28D1/32
Filed: 1982-05-28
Abstract: The apparatus comprises first, second and third splitting units (11, 12 and 13) contained in a common housing. Each splitting unit comprises two gripper members (14, 15) relatively movable towards and away from each other by power operated means (19 and 20) such that with a plate of laminated material disposed between the gripper members, the latter can be moved towards each other to grip opposing faces of the plate and then can be moved away from each other to apply a splitting strain. A trigger cut at an edge of a for desired cleavage plane is formed in the plane by a blade mounted in a carriage (22) and operated by power operated means (24). A self centering device positions the blade midway between the gripper members prior to the blade forming the trigger cut and comprises a lever arm (27) connected intermediate its ends to the carriage (22) for pivotable movement about an axis (28). One end of the lever arm is contactable by an abutment (32, 33) fixed to the gripper member (15), the other gripper member (14) being fixed or arranged to reach a set position prior to the gripper member (15) closing in on the laminated plate. The other end of the lever arm is mounted for pivotable movement about an axis (31). A spring (35) urges the carriage towards the gripper member (15). The distance between the position of contact of the arm (27) with the abutment (32, 33) and axis (27) is twice the distance between the contact position and the axis (28). A transfer mechanism (39, 41, 42) transfers laminated plate parts split in the first splitting unit to the second and third splitting units respectively. <IMAGE>

Title: Telecommunication exchange network
Inventor: REES FREDERICK HENRY
IPC: H04M7/12
Filed: 1982-07-27
Abstract: In many telecommunication exchange networks which consist of mostly of analogue exchanges (2), e.g. of the TXE4 or TXE4A type, the subscribers served include PABX's (1) which are also analogue exchanges. If any digital exchanges (4) such as System X exchanges penetrate the network, assumed to be by an overlay network connected to the existing analogue network, the subscribers served by the digital exchanges have access to more facilities than do the subscribers served by analogue exchanges. To extend these facilities to PABX subscribers, an analogue PABX (1) is provided with a digital extension unit (3) coupled to its PABX (1) via an interworking unit (5) and also coupled to a digital exchange (4) in the public network. Any call using digital facilities is set up wholly in the digital network (3, 4) while a call not using digital facilities may use either the analogue network (2, 4) or in certain circumstances the digital network. This arrangement, like that described in our Application No. 8217334, enables the PABX and its subscribers to retain their directory number unchanged. <IMAGE>

Title: Moulding composite articles
Inventor: FATTORINI THOMAS PETER
IPC: B29C33/00
Filed: 1982-10-25
Abstract: In a multi-colour moulding process, an intermediate moulded product is injection moulded in a mould having two parts 1 and 2, one part 1 of which is formed with a plurality of projections 3. This intermediate product is then removed from the mould and a desired pattern is engraved in the face thereof remote from the face in which the recesses are formed by the projections 3, the engraving communicating with the recesses. The intermediate product is then put back into the mould but this time with the part 1 replaced by a plain mould part. Moulding material, perhaps of a different colour, is injected into the mould to fill the recesses and thus the engraved pattern in the intermediate product. This arrangement permits a large number of differently patterned moulded products to be produced from the same mould. The final moulded product may be a name plate or an illuminated sign. <IMAGE>

Title: Preconditioning to reduce creep
Inventor: LINKO PETER JOHN
IPC: C22F1/00
Filed: 1982-10-27
Abstract: A metal article e.g. a gas turbine compressor casing is provided such that total expansion of the article by the process known as creep will be reduced during thermal exposure. A method, referred to as pre-creep, for producing such an article is disclosed whereby the first stage creep of the article is expended during the manufacturing cycle by application of thermomechanical processing steps. The article will operate in service during second stage creep where expansion by creep is substantially in the lowest rate range. The article in the condition produced by the method described will thereby experience a reduction in total creep during thermal exposure. <IMAGE>

Title: Power supply control
Inventor: FELLOWES COLIN VICTOR
IPC: G06F1/32
Filed: 1982-11-26
Abstract: The supply of power to a processor under the control of a programme, is controlled by a battery supervision circuit including a solid state switch, such that power is supplied in response to an input K1 from an interface (e.g. a keyboard) and is cut-off in response to a command signal from the processor. With this arrangement power is supplied to the processor only for as long as is necessary to complete the task in hand thereby increasing the efficiency of the system, more particularly the life of the battery. In order to prevent the processor operating out of control, (i.e. having failed to initialize properly) a switch control signal enabling the switch to conduct, is generated by a gate to which the input K1 from the interface and a power control signal PDC generated by the processor upon successful completion of an initializing routine, are applied whereby the power supply is shut-off in the absence of both the interface input and the power control signal. <IMAGE>
